With the continuous expansion of business development, more and more enterprises put forward the demand of networked collaborative office. How to set up a network with subsidiaries not in the same location to achieve the effect of interconnection of service applications between different places often depends on remote networking. What is remote networking? What are the ways and steps of remote networking?
What is remote networking?
To put it simply, it is the operation of interconnecting several LANs in different places into a large LAN. Because of the great differences, there are relay server support, direct connection, and a mixture of these two methods.
For example, there is a branch store in Beijing and Guangzhou. The branch cash register needs to be connected to the LAN server of the head store. There is no public IP in the gateway of the branch store and the head store. At this time, you can use remote networking to virtualize the two networks into a large LAN, and the branch cash register software can successfully access the cash register server of the head store. Of course, this is just an application. We can also realize video surveillance, NAS, OA of the unit, or the interconnection and collaborative office of ERP in the networking environment.
Introduction to remote networking mode
1. The first is to build a remote network by yourself, that is, to purchase equipment and establish a remote network belonging to you. The network demand is to rent public IP at least on one side. Except for the rental price of public IP, the price is general (equipment + address + link cost + maintenance). Maintenance requires a certain network foundation. Of course, you can also find an agent.
MPLS remote networking, as long as the traffic confidentiality is not very high, is also a relatively safe and efficient dedicated line, which is a pseudo dedicated line. The cost of MPLS remote networking is very low in the operator level dedicated line.
2. Although the traditional dedicated line can also transmit all kinds of traffic, MPLS remote networking is mainly responsible for confidential data after its emergence, which has high security and is more reliable than MPLS remote networking. The price should be the most expensive.
3. SDN network, which many companies choose now, has better confidentiality than MPLS remote networking. The price is cheaper than the dedicated line. There is no restriction. It is similar to the price of MPLS, and the effect is fast to catch up with the dedicated line. Very cost-effective.
